The Rhine Valley is storybook Germany, a fairy-tale world of legends and robber-baron castles. Cruise the most castle-studded stretch of the romantic Rhine as you listen for the song of the treacherous Loreley. For hands-on thrills, climb through the Rhineland's greatest castle, Rheinfels, above the town of St. Goar. Castle connoisseurs will also enjoy the fine interior of Marksburg Castle. Spend your nights in a castle-crowned village, either Bacharach or St. Goar.
